Re: how to copy data from watermeter to waterflow
i am using a nodemcu unit but a wemos d1 mini will work as well
input NodeMCU and Wemos D1 mini both have 3.3 inputs
sensoren work correctly on 5V
attach sensor to 5V but inputs through a pullup resistor to 3.3V

Re: how to copy data from watermeter to waterflow
Just another question: does the time value sent by esp pulsecounter is specific to espeasy? I'm wondering whether I could use Tasmota instead.
